Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an improved belt-type finger film collecting device on a residual film collector. Background Art

[0002] In Chinese Patent CN201510679669.2, a finger chain type residual film collector is disclosed. Among them, the finger chain type residual film collector discloses a film collecting device mainly composed of a finger chain. The film clamping mechanism of the film collecting device is composed of a lower film collecting sprocket, an upper film collecting sprocket, a film collecting chain and fingers, etc. After the fingers on the film collecting chain are welded to the film collecting chain at a certain angle, when the fingers rotate through the positions of the upper and lower film collecting sprockets, they will open and close, so that the film can be clamped at the lower section of the lower film collecting sprocket and opened when approaching the upper film collecting sprocket to release the film.

[0003] In practice, the design with a chain as the transmission chain has a high cost. And during the process of residual film collection, due to the gaps between the chains, the residual film will be wound around the film collecting chain, resulting in unstable working conditions and requiring manual cleaning of the residual film on the chain frequently.

[0004] In addition, using a chain as the main body of the film collecting chain also requires secondary processing of the chain, increasing the manufacturing cost.

[0005] Therefore, an improved belt-type finger film collecting device is needed, which can reduce the manufacturing cost, has no problems such as the joints of the chain links, avoid the winding of the residual film, reduce manual cleaning of the residual film, and improve the operation efficiency. Summary of the Utility Model

[0006] In view of this, to solve the problems of high cost of the film collecting chain and easy winding of the film in the prior art, an improved belt-type finger film collecting device needs to be designed, which not only saves the manufacturing cost, but also can avoid film winding, and has a simple structure and is easy to manufacture. To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An improved belt-type finger film collecting device, comprising:

[0008] Upper and lower wheels, which are respectively located at both ends of the film collecting device, the lower wheel is at the lower part, and the upper wheel is at the upper part and behind in the advancing direction of the machine. Both are rotatable.

[0009] A belt, which respectively bypasses the upper wheel and the lower wheel.

[0010] Fingers, which are integrally strip-shaped, with a connecting part designed at the bottom for connecting with the belt. The connecting part has an arc adapted to the belt and the upper and lower belt wheels, and the front end contacts the outer side of the belt or the rear section of another finger along the direction of the belt.

[0011] Preferably, the finger can also be integrally formed with the belt during belt manufacturing.

[0012] Compared with the prior art, the present utility model has the following beneficial effects: During the movement of the belt, when the finger moves above the lower wheel, since the belt moves in a circular motion along the lower wheel, the finger opens at this time. When continuing to move, the finger gradually closes, and the unfixed section of the finger and the outer side of the belt or the fixed end of the next finger clamp the film. When the finger continues to move to the straight-line position between the upper and lower wheels, because the connecting part of the finger is an arc and has a certain angle with the front end of the finger, the belt connected to the connecting part of the finger will also generate a deformation. Thus, under the action of the belt tension at both ends, the finger will have a torsional force, and this torsional force forces the finger to closely approach the outer side of the belt or the fixed end of the next finger, so that there is a certain pre-pressure between the two, and the film can be clamped tightly. And because the belt is an integral structure without the movable joints and gaps of the chain, therefore, during the operation of the residual film recycling machine, the problem that the residual film winds around the chain, resulting in a decline in the operation quality and the need for manual cleaning, can be avoided, greatly improving the operation stability of the residual film recycling machine and enhancing the operation efficiency.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "provided with", "sheathed / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] Embodiment 1: As Figure 1-2 shown, the present utility model provides an improved belt-type finger clamping film collecting device, including:

[0021] A lower wheel 1 and an upper wheel 2. The lower wheel 1 is rotatably connected near the ground below the residual film recycling machine, and the upper wheel 2 is rotatably connected above the rear of the residual film recycling machine and corresponds to the lower wheel 1. A belt 3 is wound around the lower wheel 1 and the upper wheel 2. At certain intervals along the belt 3, finger clamps 4 are fixed by bolts.

[0022] The working principle of this embodiment is as follows:

[0023] During the movement of the belt 3, when the finger 4 moves above the lower wheel 1, since the belt 3 moves in a circular motion along the lower wheel 1, the finger 4 opens at this time. When it continues to move, the finger 4 gradually closes. The unfixed section of the finger 4 and the fixed end of the next finger 4 clamp the film. When the finger 4 continues to move to the straight-line position between the upper and lower wheels, since the connecting part of the finger 4 is an arc and has a certain angle with the front end of the finger 4, the belt connected to the connecting part of the finger 4 will also produce a deformation. Thus, under the pulling force of the belt 3 at both ends, the finger 4 will have a torsional force, which forces the finger 4 to closely approach the outer side of the belt 3 or the fixed end of the next finger 4, so that there is a certain pre-pressure between the two, and the film can be clamped. And because the belt is an integral structure without the movable joints and gaps of the chain, therefore, during the operation of the residual film recycling machine, the problem that the residual film is wound around the chain, resulting in a decline in the operation quality and the need for manual cleaning, is also avoided, greatly improving the operation stability of the residual film recycling machine and enhancing the operation efficiency.

[0024] Embodiment 2: As Figure 3 shown, the present invention provides an improved belt-type finger film collecting device, including:

[0025] A lower wheel 1 and an upper wheel 2. The lower wheel 1 is rotatably connected below the residual film recycling machine near the ground, and the upper wheel 2 is rotatably connected above the rear of the residual film recycling machine and corresponds to the lower wheel 1. A belt 3 is wound around the lower wheel 1 and the upper wheel 2. At regular intervals on the belt 3, fingers 4 are fixed inside the belt 3.

[0026] The rest of the working principle is the same as that of Embodiment 1.

[0027] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
